[c-nsp] Sup720, show mmls igmp and Port-channel interfaces

[Matti Saarinen]

Hi,

I would like to find out how IOS 12.2SX displays Port-channels on the
output of "remote command switch show mmls igmp group n.n.n.n vlan-id"
command. So far I've found out that the output lists Port-channels under
non-existing module 14 eg 14/3. But the numbers after the forward slash
don't match the numbers configured with channel-group commands.

An example. The group 239.255.255.1 is used by Cisco APs that have
joined to a WiSM in this chassis. The group 239.255.255.2 is used byt
Cisco joined to a WLC pair connected via Po60 and Po61. The latter group
should be used by APs that are connected a Dell switch connected via
Po30 but I cannot find it from the show mmls output. Also, I'd like to
understand what is 14/3 in the first show mmls output.

Can anyone point me to a relevant piece of documentation explaining
these outputs?

The problem I am trying to solve is: why APs connected to Dells don't
receive the multicast traffic.

Cheers,
